312VDC (220-425V) 34cc Electric Air Conditioning Compressor - PWM (2000 to 6000 RPM) - 7ED-CF0-65E
A fully electric 312v Air Conditioning Scroll Compressor with PWM speed control. These compact units are ideal for installation into applications where belt drives are not available or space is at a premium. This compressor is very simple to wire in, and can be operated with a PWM Controller.
- Wide operating DC voltage range (220-425 V DC, nominal ~312 V) – enables compatibility with many high-voltage vehicle battery systems or DC bus architectures.
- Variable speed control (PWM, 2000-6000 RPM) – allows dynamic capacity modulation to match cooling demand, reduce energy consumption and improve comfort.
- 34 cc displacement unit – provides ample cooling capacity for cabin HVAC or thermal management systems while remaining compact in size.
- Oil-lubricated scroll or rotary design (depending on variant) – ensures reliable long-life operation, smooth performance and low vibration.
- High efficiency & compact footprint – designed to optimize space in vehicle or mobile applications and reduce parasitic load on the powertrain.
- Refrigerant compatibility (typically R134a / R1234yf) – suitable for modern refrigerants; aligns with EV/HEV A/C system requirements.
- Built for automotive / mobile harsh-duty environments – robust electrical insulation, wide ambient temperature range, sealed construction.
- Plug-and-play control potential – accepts PWM speed control signal (and potentially CAN interface) enabling system integration with vehicle control modules.
- Reduced mechanical coupling – being an electric unit, avoids belt drives, clutch assemblies and parasitic drag – simpler installation in EV/hybrid conversions.

The compressor is controlled via a PWM (Pulse Width Modulation) signal input. The speed can be adjusted from 2000 to 6000 RPM by changing the duty cycle of the PWM signal from 0% to 100%. The compressor also features a start-stop enable signal input (STB) which can be used to turn the compressor on or off.
